  • EDGE Enhanced Data for Global Evolution
  • High-speed data services are increasingly performed by way of radio communication systems. Advancements in communication technologies have permitted the development and deployment of radio communication systems that permit the communication of data at high communication throughput rates. And, with continued advancements in communication technologies, improvements to such systems permit the throughput rates to be yet further increased.
  • Various high-speed data services, and their associated mechanisms of implementation, are undergoing development, standardization, and implementation.

  • EDGE Enhanced Data for Global Evolution
  • Data throughput rates achievable in an EDGE-capable system are significantly higher than those achievable in its predecessor GPRS system.
  • EDGE-based communications permit data to be communicated at substantially higher data rates than its GPRS predecessor, data services are becoming, and anticipated to become even more so, data-intensive. There is a continuing need to find ways yet further to increase the data throughput capabilities of EDGE-based communications to facilitate the speedy communication of increasingly data-intensive data communication services that are to be implemented in an EDGE-based, or other high-speed, data communication system.
